Spring Boot 整合 spring-boot-starter-mail 实现邮件发送和账户激活

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.stereotype.Service;
 
@Service
public class MailService {
 
    private final JavaMailSender mailSender;
    private final SimpleMailMessage simpleMailMessage;
 
    @Autowired
    public MailService(JavaMailSender mailSender) {
        this.mailSender = mailSender;
        this.simpleMailMessage = new SimpleMailMessage();
        // 设置邮件的基本属性
        simpleMailMessage.setFrom("noreply@yourdomain.com");
        simpleMailMessage.setSubject("Account Activation");
    }
 
    public void sendMail(String email, String activationLink) {
        simpleMailMessage.setTo(email);
        simpleMailMessage.setText("Hi, \n\n"
                + "Please click on the below link to activate your account:\n"
                + activationLink + "\n\n"
                + "Regards, \n"
                + "Your Team");
 
        mailSender.send(simpleMailMessage);
    }
}

这段代码定义了一个MailService类，它使用了Spring Boot提供的spring-boot-starter-mail依赖来发送邮件。在发送邮件时，它设置了邮件的基本属性，如发件人、主题和邮件内容。然后，它提供了一个sendMail方法来发送邮件给用户，其中包含了用户的激活链接。这个类可以被注入到需要发送邮件的服务中，例如用户服务，当创建新用户或需要发送账户激活邮件时使用。
